ID: D Name: Date: Physics - Impulse & Momentum Multiple Choice (1 pt each) Identify the choice that best completes the statement or answers the question. 1 . A red car of mass 1,200 kg is moving to the right with an initial velocity (v ) and it collides head on with a green car of mass 2,500 kg that was moving to the left with a velocity of 18.0 m/s. After the collision, the two cars are stuck together and are not moving in either direction. What was the red car's initial velocity (V.)? A. 61.8 m/s C. 22.0 m/s E. 45.2 m/s B. 16.2 m/s D. 37.5 m/s 2. A 3000 kg truck is traveling at a velocity of 20 m/s.
